Black Opal is classified as precious Opal (as opposed to common opals which are semi-precious gemstones). It is rare, and the ones showcasing red color such as these ones, are the most desired ones.  

These precious Black Opals measuring 7 x 5 mm showcase a rainbow of colors - red, green, pink, orange, yellow -  depending on the source and direction of light. To show off the beauty of these precious gemstones they have been set in hand formed solid 18 k Gold 4 prong settings. They come with solid 14k Gold ear nuts. 

These stunning little earrings would make a wonderful gift for anyone, and especially for the ones born in October the Opal birthstone month.

Black Opal is considered the rarest type of Opal and the ones with the vibrant play-of-color such as these ones are classified as Precious Opal. Opal is often referred to as a 'living stone' - they are 'hydrophane', meaning that they absorb water and when they do their appearance changes. If the Opals come in contact with water, they will soak it up it like a sponge and in fact up to 21% of the Opal can be made of water. Therefore please take off your opal jewelry when using harsh chemicals and perfumes! 

Metaphysically opal symbolises purity and hope. It has been regarded as a protective stone, as it keeps the wearer from harm.
